In the Trilobite Wilderness, virtually every piece of extracted rock contains pieces of fossil trilobite. Not occasionally — virtually every piece. The Latham Shale Formation that underlies the Marble Mountains accumulated 500 million years ago at the bottom of a shallow Cambrian sea, and that sea was teeming. When the sediments were later uplifted to form what are now the Marble Mountains of the eastern Mojave Desert, they brought the record of that sea with them. Trilobite heads are the most commonly found feature, which scientists interpret as evidence that this particular location was a molting ground — a place where these ancient arthropods shed their exoskeletons in large numbers and left them to fossilize.

In the early Cambrian period, roughly 500 to 540 million years ago, the western edge of what is now North America lay beneath a warm, shallow sea. The sediments that accumulated on that seafloor — mud, sand, and the remains of the organisms that lived in the water — were eventual...

Twelve trilobite species have been identified in the Trilobite Wilderness, with specimens from the order Olenellina predominating. Olenellids are among the earliest trilobites to appear in the fossil record — their presence in the Latham Shale places this formation near the base ...

The Trilobite Wilderness was added to the National Wilderness Preservation System in 1994 as part of the California Desert Protection Act — the same legislation that established Joshua Tree National Park and Death Valley National Park in their current boundaries. The wilderness d...
